WILLIAM PAUL BUTUSOV, OF TAMPA, FLORIDA.

AERPLANE.

To all ywhom t may (fo/acorn.'

, lle it known that l. il/vimini PAUL ll irrita/or, a citizen of theUnited States, and a resident of' Tampa, in the county of Hillehorougliand State olf Florida, have invented certain new and nseiullniproif'enienta` in Aeroplanea oi which the following ie a Fig. 5 is apartial perspective View loolzing at the front.

ln the present embodiment of the inve-ntion, the improved plane whichmay he of any usual Constrnotiony being a bi-plane in the presentinstance, ie composed olE the fuselage 1, having the upper and lowerwings. Q and 3 and the usual propeller' -l arranged at the firent 01"'the planes and with its axis near the upper plane 2. 'lhe e iait 5 oi'the lpropeller is journaled just below the center of the upper plane 2and on ea 'h eide of the fuselage in liront or" the wings there isprovided a nose plane G. These planes (i are secured to a 'eonnnon shaftT. and they are normallj;T held in the position shown in Fig. l by meansof eoui1tei-\veights 8, the said Counter-weights being connected to theplane frames by hangers 9.

A rod l0 ie hinged to a plate l1 forming'a part of the fuselage betweenthe planes 6 and below the same, as indicated at 12, and this rod isconnected to the shaft as shown in 2 by nieane of a latch 13. The np perend of the rod oarrieg a ball or Weight lll, and between the hall andthe latch 13 the rod passes through slot lo in a rod 16 extendinglongitudinally of the fuselage.

:it Willbe noticed that the shaft i' has Specification of LettersPatent.

Application filed April 25, 1919. Serial No. 292.626.

a flattened portion at the latch 13.l and that the latch has varme forengaging the {iattened portion above and below the shaft. llVhen the rodis swung forwardly away from the. shaft, the lateh will released.,permitting theinose planes to n'ioye. While when the latch is in theposition of Fig. 21 the Shaft is locked freni movement. The rod may beoperated by the bar or rod 16.

A stabilizing fin l? is arranged between the planes 2 and 3 and therudder post 18. the said fin being vertical, and, beingat the center ofthe fuselage. The vertical rudder 19 is connected to the post 18ersshown. and horizontal rudders 20 are arranged at the opposite sides ofthe vertical rudder.

Banking planes 21 are provided at the ends of the planes 2 and 3` the`said banking planes being arranged lin inclined position between theplanes :2 and Referring' to Fig. 5, it will be noticed that the bankingplanes incline ontnf'ardly toward their upper ende. llie inclination ofthe banking planes is and these planeo are stationary.

The nose or dipping planes are on each eide of the oook-pit, and theyare normally locked, but will release automatically. to prevent nosedive and to bring` the machine hack to a normal state, after which theplanes will look with the look bar or rod 16 which is in front oi theoperator.

The banking planes 2l 'will prevent banking; or skidding, what isdesignated as going oil on the wing. The stabilizing tin extending fromthe main plane to the-rudder, prevents the machine from rocking; andfrom skidding'. AWhile the Aimproreinent is shown applied. to one torniof flying machine. it will he understood 'that it may be applied to anyform with equal faoility.

I claime- 1. ln a fyix'ig machine, the Combination with the fuselage,the main supporting planes and the rudder7 oi banking planes arrangedbetween the main planes at the ends thereof in inclined position, astabilizingn lin extending between the main planes and the rudder invertical position, and nose planes at the front oi' the 'fuselage oneaeh Side thereof. and eounterweightl-f to hold normally apredeterniined potution, and means for locking the nene ph ree againstmovement.
